change main page redirect to be more search engine friendly (added line in htaccess - seems that default behavior is to use temporary redirects - need to research further, later)

work on Main_Page overall user interface, address feedback to be more intuitive and user friendly... "more like a directory"? Possibly list categories on Main_Page for easy browsing (like other directories).

do simple validation on new directory entries (looks like it could possibly be a domain?)
